    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

it has potential try a larger line width!

May be something like this? x.lineWidth=9;t?x.strokeStyle=hsl(${t*99},90%,60%:x.fillRect(0,0,Z=2e3,Z);x.strokeRect(S(t*Z)*Z%Z,t%2*540,69,69);x.drawImage(c,S(t),C(t))
